To explain this in the simplest of terms, say you type a web address, like www.youtube.com in the web browser, your computer queries a DNS server to find the matching IP address where that site is situated and once it has that information, it routes your browser to the correct website.

That is probably the ultimate and most basic definition of DNS, but behind the scenes, a number of parties could get drawn in as soon as your computer asks for the IP address of a domain name. There’s the Resolving Name Server, the Root Name Server, the TLD Name Server and finally, the Authoritative Name Server.

Domain Name System (DNS)

How To Choose Domain Names

It is important to choose the right domain name to ensure that your website is a success. The problem is, because of the massive amounts of domains that are in use, finding a good domain name can be a daunting task.

1. You need to find a domain name that fits your website, that, if possible, describes your business or its basic purpose.

2. If possible get a .com address. A lot of people connect websites with the .com ending. Should the core domain extension of .com be unavailable, consider .net or .org. Many alternative domain name extensions such as .biz and .tv can be considered as well.

3. Keywords are an important consideration in your domain name, as including them will boost your search engine rankings. You should begin by seriously thinking about a list of keywords that could be used to identify the type of business that you are registering the domain for. For example, if you sell jewelry, “diamonds.com” would be a suitable domain name.

4. Don’t overdo it. Choose an uncomplicated domain name. Your domain name must be short, easy to spell, or contain normal, well-known characters. Three words long would be perfect, with no hyphens and avoid any complex words. As was seen in our earlier example, “diamonds.com” is short and quite unforgettable. A domain such as “diamonds-new-and-old.com” is much longer and rather tricky to remember.

Web Hosting Explained.

Effective web hosting is a provided service that enables businesses and persons to post a website or web page onto the internet. A web host, or web hosting service supplier, is a business that offers the technologies and services desired for the website or webpage to be visited on the internet. Websites are hosted, or stored, on specially constructed and programmed computers called web servers.

DNS is an acronym for Domain Name System, which is a system of computers that makes the infrastructure available for allowing the effective browsing of the world wide web. In its most simplified form, the Domain Name System is an assembly of root servers that host the Internet Protocol (IP) addresses of the DNS name servers that have influence over individual domains of every registered internet domain name.

The specific function of the DNS name servers serviced by your hosting company is to react to a query for a specific domain name with the exact locality on the exact web hosting server (using that server’s IP address) where that domain name, and thus web site, is situated.

What should be very clear by now is that a DNS server is vital to the proper functioning of the web. Without DNS, there would be no web.
